description
Built on LABEKS’ years of expertise in spectral instrument design and manufacturing, the L-U7 series of double-beam UV-Vis spectrophotometers incorporates an optimized optical path, high-sensitivity photomultiplier tube receiver, and globally sourced premium components. Delivering superior performance, these instruments fully satisfy the stringent analytical requirements of professional users, and are widely applied in scientific research and industrial production across fields including organic chemistry, biochemistry, pharmaceutical analysis, food inspection, healthcare, environmental protection, and life sciences.
Equipped with a pulsed xenon lamp as its light source, the L-U7 operates reliably for a minimum of 7 years without needing lamp replacement, minimizing long-term operational costs for users. Crafted with proprietary optical, circuit, and structural designs, paired with advanced manufacturing processes and a strict quality management system, this instrument meets international advanced standards while aligning with user requirements and operational habits. Microcomputer-controlled data processing, a large color display, graphical interface, and intuitive menu prompts enable immediate spectral mapping and test data analysis. It offers comprehensive functions including photometric measurement, automatic spectral scanning, quantitative analysis, and dynamic spectrophotometry, boasting high analytical sensitivity and accuracy, robust spectral data processing capabilities, user-friendly Chinese human-machine interaction, streamlined operation, and an elegant, professional appearance.
features
1. Featuring a suspended optical system and reinforced thick aluminum base plate, it eliminates the impact of vibration or deformation on the optical system. The double-layer design fully isolates optical and circuit components, avoiding opto-electronic interference even during instrument maintenance, thereby enhancing the instrument’s resolution and stability.
2. Equipped with the national patent photoelectric signal detection device (Patent No. ZL 2010 2 0562320.3), the instrument achieves a lower signal-to-noise ratio and improved overall stability.
3. As an industry pioneer, this spectrophotometer adopts the advanced ARM12 processor, capable of storing up to 5000 test datasets or 500 calibration curves.
4. Boasting a 10.1-inch color touchscreen, the instrument directly displays diverse scan curves and graphs, enabling users to fulfill all measurement requirements independently without relying on an external computer.
5. The instrument offers versatile data output options: RS-232C serial port for printing, USB drive for online data transfer, and USB HOST for USB disk connection, with 16GB of standard built-in memory.
6. USB drive storage is supported for straightforward use. User-measured data can be directly exported to a USB drive, and no specialized auxiliary software is required to open or edit the data. It supports output in Excel, TXT, and image formats (including four specific formats: *.csv, *.qua, *.tet, *.bmp), enabling users to directly edit experiment reports on a PC while significantly saving lab bench space.
